There seem to be a COLLABORATIVE effort by the Malaysia-Singapore federation in military procurement. The combined military budget of the collaboration federation states is about US$16 billion a year.

Singapore buys AMERICAN aircrafts, missiles.
Malaysia buys RUSSIAN, and now it appears French aircraft, missiles.

Both Singapore and Malaysia buys British basic aircraft, air defense, French naval assets.
For small arms, both Singapore and Malaysia manufacture it's own! (Malaysia seems to be downsizing it's Army unit numbers, and diverting funds to buy naval, air armaments!)

Cool, isn't it.
Global geopolitics, our nations has to strategic purchase from all the BIG POWERS in the interest of friendship and mutual support!

and in Malaysia, the Royal Malaysian Units possess a couple of battalions of T-91 MBT.

Main Battle Tanks IN SOGGY, SOFT SOIL tropical region of the Malayan peninsular! Come on! These sibling rivalry games is getting crazy! APC would be more suitable, combined with an efficient ENGINEERING CORP would suit the SOFT SOIL conditions blanketed with rivers, canals, sudden flash flood geography and climate much better! It's only use is SPEARHEAD CHARGE, post softening by the Air Force, and Artillery carpet bombardment! Alas on MAJOR ASPHALTED, heavy load highways only! (so much for all terrain for these >60T heavy vehicles)

(Fortunately we have the Malay Regiment, Borneo Rangers - which are mainly INFANTRY, and Air Calvary savvy)

Singapore-British secret collaborations - LASER or PARTICLE gun. The weapon is capable of DESTROYING incoming CRUISE MISSILES. Singapore Home Guards has these weapons since 2005.

The Royal Malaysian Armed Forces possess the MICROWAVE gun. These is used up to 1 GW/mm2 focused MICROWAVE with the same capability to IMMOBILIZED incoming CRUISE MISSILES. Test has been ongoing in Malaysia with vendors for quite some time already!

The Singapore Home Guards possess a squadron of these AIR INDEPENDENT PROPULSION submarines. It will be quite deadly for any incoming ENEMY EXPEDITIONARY FORCES, including aircraft carriers or amphibious carriers.

The Royal Malaysian Forces possess a squadron of SCORPENES air independent propulsion submarines. It's guards the South China Sea while the Singaporean squadrons guards the Indian ocean access!

Battle tested Garrison Troops, well trained by the British. Many of the senior Malay Regiment Officers are graduates of the famous Sandhurst Military College in England.

The TOUGH Borneo troops of the ROYAL MALAYSIAN RANGERS!
(We have a joke during our youth - pork eating Malay soldiers)

The crack regiments are INCREDIBLE JUNGLE WARFARE specialist. Even the US Army trains in Malaysia to gain experience of Jungle enviroments. The BORNEO RANGERS are a tough bunch which no army in the world would dare to take on.
